PICKER-STICK CHECK.

Application filed April 14, 1923.

T 0 all whom it may concern:

Be it known that we, JOHN HERBERT and JAMES A. ANDREWS, citizens of the United States, residing at Biddeford, in the county of York and State of Maine, have invented new and useful Improvements in Picker-Stick Checks, of which the following is a specification.

This invention relates to certain new and useful improvements in picker stick checks and relates more .particularly to an improvement upon our Patent No. 1,894,265.

The primary object of the invention is to provide means for enabling added friction to be imposed on the check strap to any desired extent, which means is also capable of easy and quick adjustment to afford the desired degree of friction.

A. further object of the invention is to provide a friction device for the purpose specified which is of economical, compact and simple construction and which is positive in operation. v

Further and other objects will be later set forth and manifested in the course of the following description.

In the drawings z- Figure 1, is a side elevation of the invention;

Figure 2, is a bottom plan view thereof;

Figure 3, is an enlarged detail side elevation of the improvement, and

Figure 4, is an enlarged detail bottom plan View. of the improvement.

In proceeding in accordance with the present invention, the lay 1 has the usual pick stick 2 movable therein and checked in its oscillatory movements by means of the endless-check strap 3. 'The check strap on one side is supported and guided by means of an inner finger 4 having a ledge or lip 5 and a pair of spaced outer fingers 6 and 7. The finger 4 isarranged in the space between the fingers 6 and 7 engages one side face of the strap while the finger 4 engages the opposite side face of the strap. p

A bracket 8 attached to the lay 1, supports the finger 4, While the fingers 6 and '7 are carried by a frame 9 which is adjustably secured to the bracket 8, by a nut and bolt 10. A fourth finger 11 overlies the finger 7 and cooperates with the upper face of the latter to hold one end of a substantially J-shaped and relatively stiff friction member 12, the latter being formed of the Serial No. 632,100.

same material as that of which the strap 3 is formed. The finger 7 thus functions in a dual manner, namely to afford a friction creating medium or support for the check strap 3, and a jaw cooperating with finger 11, to clamp one end of the J-strap or friction element in position. The opposite end, at the shorter leg, of the J-strap is clamped in position between jaws 13 and 14 carried by an arm 15,'the latter being adjustably clamped by a bolt and nut 16, extending through a slot 17 formed in the frame 9.

The J-shape of the friction member12, affords a nose 20 whichengages a side of the check strap 3 to increase the friction of thelatter. By vertical adjustment of the arm 15, obtained by movement of the bolt 7 16, in the slot 17 the friction exerted by the nose 20 on the checkstrap 3, may be regulated, as desired.

It will further be noted that the frame 9 which adjustably carries the arm 15 has its bolt 10 disposed in a slot 21 in the bracket 8 so that by vertical adjustment of the frame 9, the fingers 4 and 6 and 7 will be adjusted, and at the same time the nose 20 of the friction strap 12, will be adjusted. However, the nose 20 can be adjusted independent of the adjustment of the fingers 4, 6, and 7 through means of. the bolt 16 and slot 17, to thereby additionally friction the check strap 3.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent is 1. In a pick stick check, a check strap, a bracket formed for attachment to the lay, a frame adjustably carried by the bracket, a pair of spaced fingers carried by the frame and engaging one face of a side of the strap, a third finger carried by the bracket and disposed in the space between the pair of fingers and engaging the opposite face of said side of the strap, a fric-v tion strap of approximately J-shape having one end engaged with one of the fingers of the pair of fingers and its nose engaged with a side of the check strap, an arm having a clamping jaw engaged with said end of the J-shaped strap to hold the latter on said end of the J-shaped strap to hold the latter on said finger of the pair of fingers, a pair of clamping members receiving and holding the opposite end of the J-shaped strap therebetween, and means to adjustably connect the arm to the frame so as to enable the degree of frictional engagement of the nose of the friction strap with the check strap to be regulated.

2. In a pick stick check, a check strap, a bracket formed for attachment to the lay, a frame adjustably carried by the bracket, a pair of spaced fingers carried by the frame and engaging one face of the strap, third finger carried by the bracket and disposed in the space between the pair of fingers and engagingthe opposite face of said side of the check strap, a friction strap having an intermediate part engaged with the check strap and having one end engaged with one of the fingers of the pair of fingers, an arm having a clamping member engaged with sa'idend of the friction strap to hold same on said finger of the pair of fingers, a pair of clamping members for holding the opposite end of the friction strap, and means to adjustably connect the arm to the frame so as to enable the degree of frictional engagement of the friction strap with the check strap to be regulated.

In a pick stick check, a check strap, a substantially J-shaped friction strap having its nose engaged with a side of the check strap, and means to effect adjustment of the nose to vary the friction thereof on the check strap.

4. In a pick stick check, a check strap, means to vary the pressure on the strap, and a curved friction strap for frictioning the check strap engaged with the outer side of the latter.

In a pick stick check, a check strap, means to vary the pressure on the strap, a friction strap having an intermediate part engaged with the check strap and means to mount the friction strap independent of the check strap.

6. In a pick stick check, a check strap, means to vary the pressure on the strap, a friction strap having an intermediate part engaged with the check strap, and means to mount the friction strap independent of the cheek strap and to effect adjustment of the friction exerted by said intermediate part on the check strap.

7. In a pick stick check, a check strap, a friction strap curved to form a nose between its ends, and means to secure each of the ends of the friction strap so as to cause the nose thereof to frictionally engage the check strap.

8. In a pick stick check, a check strap, friction creating means including a strap formed of the same material as the strap engaging the latter and means to mount said friction creating means independentof the check strap.

9. In a pick stick check, a check strap, a friction strap having a curved part between its ends, means to secure each of the ends of part engaged with an outer face of a side of the check strap, and means to mount the friction strap'independent of the check strap to cause same to frictionally engage said side of the check strap.

11. In a pick stick check, a check strap, a friction strap having a curved intermediate part engaging a face of the check strap and means to rigidly support each end of the friction strap.

12. In a pick stick check, a check strap, a friction element having ends and a curved part intermediate the ends, means to mount one end of the element and means to adjust ably mount the other end of the element to vary the pressure of the curved part on the check strap.

13. In combination with a check strap and means to exert pressure thereon, a friction element, having ends, means to secure one end of the element to said pressure means, and means to adjustably mount the opposite end of said element to cause the latter to exert predetermined friction on the check strap.

14. In combination with a check strap and means to exert pressure thereon, a friction element having ends, means to secure one end of the element to said pressure means, and means to adjustably mount the opposite end of said element to cause the latter to have an intermediate curved part which engages the check strap with predetermined friction.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
